CHAPTER 5,2 ENGINEERING ORGANIZATION The planning, development, and operation of the proving grounds at Eniwetok involved various phases of engineering, both in the office and in the field, and required specialists in site planning; in architecture, civil, mechanical, electrical, structural, sanitary, electronic, refrigeration, and air-conditioning engineering; and in communications, power generation and distribution, water distillation, land and hydrographic surveying, and materials testing, Although this Project was possibly more involved and diversified than some projects that have been successfully carried out over a period of years by the Engineering Division of Holmes & Narver, Inc., it did not impose a severe personnel burden on the Engineering Division, In fact, all of the engineering requirements were carried out by the Engi- neering Division as already organized, Additional personnel were placed under the direction of key men who had been directing engineering design for H & N for years, There were three principal types of engineering work on the Project: field surveys, design, and field supervision and inspection, ° 2 we WN bf Field surveys consisted of the following: 6, 7, Horizontal and vertical control surveys Topographical surveys Hydrography Mapping of experiment islends Construction surveys (location on ground of structures, roads, and utilities) Cross-sectioning of zero areas before and after tests Remapping of all islands after tests to show surviving structures and new shore line Surveys were under the direction of the Chief of Surveys who was a member of the initial party sent to the Jobsite on Februery 1, 1949. He or his replacement was at the Jobsite throughout the development and construction period, The Chief of Surveys reported directly to the Resident Manager at Jobsite until the Engineering Manager was appointed on March 1950, Design information obtained by surveys was forwarded to the Chief Engineer for use at the Home Office by the Engineering Division, Design, under the direct supervision of the Chief Engineer, included all work carried on by the Engineering Division at the Home Office, consisting of the following: 1. 5-6 Preparation of preliminary drawings and sketches based on information furnished by J-Division of LASL,
